30 Passive Income Ideas You Can Use to Build Real Wealth

#22 Sell An Online Course

This one is similar to selling an ebook since it benefits those with specialized knowledge in a particular area or field.

Courses for things like web design, marketing, and buying real estate are especially profitable.

Using simple slideshows or screencasts, you can teach people what you know and make money off the information that you pass down to them.

Some people might claim that this is a pyramid scheme. But if you believe in what you’re teaching and approach it honestly, then selling an online course can be extremely lucrative for you.
